f 5 oiaims. (o1. 72-'41) My improved construction is applicable towalls formed of either solid or. hollow building blocks and it may be used in a wall of the thickness of a single'blo'ck or as an interior backing for a wall 5 of any'thickness;Y

VThe object of my invention is to provide such walls with ribs,formed integral with the blocks themselves, between .which are formed spaces for theV reception of bats'of resilient insulating ma- 'teriaL such ribs serving as means for holding the insulating material inplace while metal lathin is secured to the outer face of the ribs.

In the' drawing'Fig. lis a perspective view of two walls forming a corner of a room or buildl5 ing. Fig. 2 shows perspective views of two forms of building blocks which are used in alternate courses of the wall. Fig. 3 isran irregular section taken on the line 3 3 Fig. l. Fig. 4 is an elevation of a modified construction of building block 20 and wall.

With the object above stated, I may construct i my improved wall of two courses of building blocks, those of course A being provided on their interior Vexposed face with a vertical rib or lug a 25 at each end, one face of which is substantially iiush with the end face of the block while the opposite side of the rib is inclined outward from the face of the block to the outer face of the rib, the latter being a trapezium in cross section, with its shortest parallel side against the face of the block. The blocks of course B are provided at the central point of their inner face with an integral vertical rib b the cross section of which is just equal tothat of the two adjacent ribs a plus the thickness of the mortar joint so that when the blocks are laid in the wall to break joints, in the usual manner, the end ribs Va will lie immediately over and under the central rib b of course B and, together therewith, will form continuous 40 vertical ribs or furring strips the cross section of which is of dovetail form.

As the wall is being built, a metallic tie C of any form which is provided with a head or shoulder and a point of sunicient length, such as a nail,

45 is laid in each mortar course at the joints between the blocks of course A, with the point projecting from the outer face of the rib, so that the head will be embedded in the mortar and the point will serve as a securing device for the metal lathing D. The metal lathing D cornes in sheets or rolls and is stretched over the outer face of the ribs and impaled on the pins C which are then bent over the same to secure it in place. 55 Any form of interior finishing surface, such as Y plaster or tiling, may be laid upon the lathing in the usual way. The ribs not only serve as furrng strips but add strength and stiffness to the wall and may be used to support the oor joists and rafters of the building. Such a block is substan- 55 tially as strong as if its inner face were ush with the outer face of the ribs. j v l A modied form of integral furring striprmay be produced by using blocks E of Fig. 4 a form,

in which a dovetail rib g is arranged horizontally l0! on the exposed face so that the blocks in a given course will'form a continuous horizontal rib. In

this-form' the pins orties C" may'belaid inthe mortar joints at any desired intervals. This form of block could also be used with intermediate courses of ordinary plain blocks which will provide space for insulating bats of any desired widths.

At the present time there is a growing demand for the heat insulation of buildings and my improved construction provides a convenient means for the application of insulation to the walls as they are being laid. The principal insulating material used for this purpose is what is known as rock wool in the building trade, which comes in the form of bats, like cotton batting, of any desired width and thickness. In my improved wall construction, prior to the attachment of the metal lathing, a. sheet of rock wool W may be laid in the space between the continuous ribs and sprung beneath the inclined edges which will hold it in place while the metal lathing is applied. In this way the insulation is added without increasing the normal thickness of the wall or decreasing its strength. The ribs might be of right angled cross section, so far as their furring function is concerned, but such a construction would necessitate the use of some form of securing device to hold the insulation in place while the lathng is being applied and is less desirable for that reason.

In forming a corner, the blocks, which break joints in the two courses, would alternately overlap and where the ribs would interfere with the abutment of one block against another they may be readily broken off, as illustrated at the points e and f.

Having thus described my invention, what I wish to claim is: 1. A masonry wall for buildings constructed of building blocks, some of which are provided on their interior exposed face with integral ribs which, when laid in the wall, are aligned to form parallel recesses between their sides for the rel au,

ception of bats of heat insulating material, said ribs being formed with overhanging edges along the sides of the recesses for supporting and holding the insulating material in place While metal lathing is being secured to the outer face of the ribs. Y

2. A masonry wall for buildings constructed of building blocks, some of which are provided on their interior exposed face with integral vertical ribs which, when laidin the wall, are aligned to form parallel recessesbetween their sides `for the reception of bats of heat insulating material, said ribs being formed with overhanging edges along:` the sides of the recesses for supporting and holding the insulating material in place while'metal lathingis being secured'to the puter face of the`- I Hserted inthe mortar at the joints of the rst ribs.
